Description

It takes a substantial amount of power to run the entire electronic system in vehicles today. Automobiles are built to handle all these electronics, but not all small recreational vehicles can. When a small recreation engine is used for the Formula SAE event, electronics like fuel injection and data acquisition systems are added to the vehicle for performance and reliability. With these additions, the electronic power output of the charging system must be evaluated and upgraded if needed. Failure to have a proper charging system can result in a poorly running vehicle or a vehicle that does not run at all. After using an amp clamp and volt meter to measure the stock charging systems performance, a new upgraded system consisting of the stator and voltage regulator was researched and developed to test. The testing was done by putting maximum electrical load that the recreational KTM 525 motor would see, while making sure that the battery was still able to charge. The research paid off as the new charging system outputs about 35 percent more power than stock at 3,800 RPM. This is enough power for all of the electronics and charges the battery adequately. This research helped develop an understanding of charging systems and how to build one based on how much power is needed at a specific motor speed.
